Note 1/10/2012: If one uses an IDE such as Code::Blocks (www.codeblocks.org), SHAPEFS should be mostly platform independent, much like GIMP itself. Sincere apologies to any users attempting to use this plug-in. Life intervened between the time I created this and today. I'll take your advise and insure that any future versions come with the correct configure scripts as with other Linux source packages.
A set of gradients for toning B&W photos. New are multi-colored toning gradients (thanks Ron Antonishen for the conversion script), and 3 Albubum print gradients. Instructions for use are in the README file.

After you download the script to your scripts folder and refresh your scripts (Filters -> Script-Fu –> Refresh Scripts), you'll find the new script in the menu under Script-Fu> Darla –> Saturation Fix.
